Official observations from the National Environment Agency (NEA) stations across Singapore, including Changi, confirm the daily maximum temperature reached 33°C on April 8 amid inter-monsoon conditions featuring afternoon thundery showers that increased cloud cover and suppressed further heating. NEA's fortnightly outlook anticipated highs of 33–35°C, but persistent showers aligned with historical April patterns—where average maxima hover around 32–33°C—capped peaks at the lower end, driving trader consensus to near-certainty on this outcome as the day nears resolution. Realistic challenges include a late revision from a peripheral station exceeding 33°C or an unverified outlier reading, though unlikely given midday peaking norms and declining solar angles. NEA daily records expected by the 10th will finalize.
